X + x - 8 + x/2 - 4 = 38
2x + x/2 = 38 + 8 + 4
5x/2 = 50
5x = 100
x = 20
that the amoint of water : 20
amount of rubbing alcohol: (1/2)(20-8) = (1/2)(12) = 6
difference : 20-6 = 14
hope this help
The area of the section described above is . The solution was arrived at by using the knowledge of the area of polygons.
<h3>What is the solution to the above question?</h3>
To solve the above, one would need to first derive the area of the polygon, then derive the area of the inscribed circle.
The area of the circle will not be removed from the area of the polygon to find the area of the silver portion.
See the attached for the full solution.
